Studies on [Pt(II)(di-tert-butylSalophen)] which is thermally stable (Td = 390°C) and displays a deep-red emission (Imax = 660 nm) are presented. Based on efficient energy transfer, this Pt(II) complex was used as a probe for exciton formation in organic light-emitting diodes (OLEDs). Electrical characterisation of host-guest system based devices showed that the presence of the Pt(II) complex within...
Electrostriction is based on the variation of permittivity of a dielectric material when subjected to mechanical strain. Until now, the use of electrostrictive materials is limited to the actuation of Micro Electro Mechanical Systems (MEMS) operating mostly in static mode. Here, we present the use of electrostriction as integrated transduction scheme in organic microcantilevers operating in both static...
The majority of innovative trends in automotive industry today relies on electronic systems. Understanding the electromagnetic behavior of the electronic control units (ECUs) in a vehicle has become an ever increasing concern of automotive manufacturers. Computational Electromagnetic Modeling (CEM) is a cost effective approach that has being adopted by the automotive industry to address electromagnetic...
We present a study of the pattern effects induced by spike and laser anneals in LP 45 nm CMOS platform. A complete optical and thermal simulation methodology that provides the intra-field temperature mapping has been developed and validated by electrical measurement. This work enables significant improvements, by decreasing the optical dispersion, through an optimized dummification at long and short...
Local thermal variation occurring during light enhanced rapid thermal process (RTP) and millisecond anneals called “pattern effects” have various origin, with more or less impact as function of the used process. The main issues concern the variation of thermal conductivity and the variation of the light absorption by optical interference or diffraction effects. In this paper, a large panel of experiments...
The aim of this paper is to demonstrate that vibrating microcantilevers can be used (1) to measure the viscosity of a Newtonian fluid for a wide range of viscosities and (2) to determine the viscoelastic properties of a Maxwellian fluid. To widen the viscosity measurement range of more classical microcantilever-based viscometers, the frequency spectrum of a vibrating microcantilever is studied instead...
